WHITE CREEK, N.Y. (AP) — A car belonging to an ex-convict wanted for questioning in a New York house fire that killed his mother and two others was discovered Wednesday in New Hampshire, but the man, his girlfriend and their infant son were nowhere to be found.

Matthew Slocum is the son of Lisa Harrington, who died in the fire early Wednesday along with her husband, Dan, and his son Josh in White Creek, 35 miles northeast of Albany, state police said.

Slocum may be holding his girlfriend, 25-year-old Loretta Colegrove, against her will, along with their infant son, Raymond, police said. Amber alerts were issued in New York and New England.

The 23-year-old Slocum is described as about 6 feet tall and near 200 pounds, with swastika tattoos on his arms. He was seen wearing a black T-shirt with a skull and crossbones on it.

The alerts were issued after Slocum left the burning home in a black 2003 Ford Mustang. He was reported near Adams, Mass., at about 5 a.m., and authorities said the empty vehicle was found late Wednesday afternoon in Gilsum, N.H., 75 miles northeast of there.

Guns known to be in the home couldn’t be accounted for, and police told the Glens Falls Post-Star they were asking neighbors whether they heard shots before the fire.

Dan Harrington was a deputy highway superintendent. “They were good people. Dan was a real good employee,” White Creek town Supervisor Bob Shay told the Post-Star. “We all feel horrible. It’s just so sad.” He said Harrington and his wife served on the town recreation committee.

Slocum went to prison in 2006 for breaking into a house and stealing cash, a New York prison spokesman said. He was released but returned to custody twice for violations before his parole expired in December 2009.

On Wednesday afternoon, emergency crews remained on the scene of the charred remains of the house, set back from a remote country road on heavily wooded property. Police haven’t released any information about the cause of the fire.
